The ancestor of the KGB was the CHEKA. In the beginning, the CHEKA was conceived and operated almost exclusively by Jews.

Jews were not the only ones but their operational influence was huge.

The first head of the CHEKA was Moses Uritsky (Jew). His successor was a person of dubious "Polish" origin named Felix Dzerzhinski, but it was common knowledge that he didn't care and was overshadowed by his nominal subordinate, I. S. Unschlicht (Jew). Over the years, control of the torture apparatus has been passed to Genrik Yagoda (Jew), Lavrenti Beria (Georgian) and Yuri Andropov (Jew).
